Application led April 2, 1906. Serial No. 309,277;

To all whom 'it may concern:

Be it known that I, HENRY D. Fnnxr, a citizen of the United States, and resident of Glencoe, in the county of Baltimore and State of Maryland, have made a certain'` new and useful Invention in Machines for Manufacturing Grain into Form for` Food;I and l declare the following to be a full, clear,"

Figure l is a vertical longitudinal sec-v tional view. Fig. 2 is a transverse sectional view. Fig. 3 is a top view. Fig. 4L is an enp' larged partial longitudinal section. Fig. 6 represents details yof the perforated pan.

Fig. 7 is a sectional view of the differential pulley. y

The object of the invention is to provide means for reducing cooked grain to short uniform lengths of attenuated form and rough or crenated exterior, separate from each other, crisp and tender in structure, and agreeable in appearance as a breakfast food.

In the accompanying drawings, the letter a., designates a press; o, a cylindric press casing or receptacle open at both ends, which is designed to be placed in the seat of, of the press frame, and is removable therefrom. In axial line with the seat d, is the follower e, of the press, which is designed to be actuated by means of a screw f, in connection with operative gearing having a quick movement of reversal.y As illustrated, the follower is below the seat d, and is so arranged thatthe -cylinder can be readily placed-in said seat and removed therefrom.

Axially above the cylinder is located l anv opening or mouth lw, of rectangular shape, 0r having parallel margins 6. This mouth is designed to be smaller than the openings of the press cylinder, and is formed with an upward sloping throat wall 7, having its lower opening provided with a seat 8, designed to be engaged by the upper edge of the press cylinder. The parallel edges 6, of

the mouth extend transversely of the frame, which is provided with extensions in front and in rear thereof as indicated for tables or endless carriers 9, flush with said mouth.

rllhe frame is provided with suitable means for forcibly moving a perforated plate carrier in its plane across the press mouth fw, in the direction of the length of the frame, and at right angles to the edges 6, of said mouth, which is designed tol keep the length of the product uniform, and is the chief factor in governing such length.

The perforated or wire cloth plate g, in the drawing, forms the bottom or base of the carrier or pan 7L., which is designed to be guided in its movement along the frame by suitable ways. The perforated plate is preferably made of sheet tin, or, it may be made of plate steel with thin edge perforations, so that it will not form a smooth, round product, but will allow the material to pass in crenated orrough form depending on the movement of the material in the cylinder, and on the movement of the carrier.

The reduced or ground grain deprived of the hull or outer coat is placed in a closed receptacle or in a cylinder o, closed with air-tight caps. The material is cooked by immersion in boiling water, or in a steam chamber for a suitable time, in the case of ground corn, about seven hours, the amount of water being about equal to that of the grain material with which it is mixed, or such that it will be absorbed by the material, and result in a semi-solid or hardened mass. When it is cool, the cylinder charged with the material in this cooked form is placed in the press,.the operation of which by suitable mechanism, not only actuates the follower e, but also moves the perforated carrier across the press mouth. As the follower moves slowly upward in the cylinder, the perforated carrier also moves slowly across the press mouth, andthe material pressed through the moving perforations is formed by continuous accretion into upright lengths or sprays, having a rounded and crenated or rough exterior and substantially uniform length.

The pans or carriers are designed to t together closely end to end, and a number of them are employed in connection with the machine, which, when the carriers are fed to the press in succession, and in closed endwise relation, can be operated in a continuous manner. For this purpose, the carriers are placed in engagement on a feeding belt or chain device mounted on the frame eXtension, as indicated at 10. In a similar way, the carriers may be moved "from the press mouth, as they become charged with the formed sprays, on -a belt device in their transition to an oven or drier. The consistency of the material in the cylinder is designed to be such that the sprays will remain in vertical position on the perforated bottom of the carrier, and, beingheld in such position by their terminal attachment to the perforations, will maintain each its separate position. In vthis way, it is designed, not only to prevent the sprays from adhering to each other in bunches, but also to facilitate the access of warm air to all ,parts thereof to quickly and uniformly kdry the product. f

In order to facilitate the passage of the perforated carrier plate across the press mouth, where the pressure of the material tends to force the platel awa-y from its bearing on the edgesof said mouth and produce a loose joint through which -the material may waste, means vare provided Yas follows:

'ln order to loosen up the material just before it engages the perforations of the plate, horizontal ribs 7c, eXtending across the throat or passage to said mouth just below the plane of its edges are located in said throat or passage. These ribs not only serve to lessen the pressure on the perforated plate,

but they also assist in working the material to homogeneous character at this point, and

in causing its constituent particles to move easily with relation to each other, so that it will pass readilyvv through the perforations.

, tributey the pressure over its surface. When they perforated plate employed is made of plate steel and has its perforations bordered with thin edges, the ribs are not required and the pressure wheels may engage the surface of the plate between the rows of perforations. These perforations are usually made about one-sixteenth of an inch in diameter, to produce sprays of less than an inch in length. The distance between the limiting edges 6, of the press mouth may be about an inch and a quarter. The rate of motion of the perforated carrier may be adjusted to suit that of the press follower by means of an adjustable differential pulley device 15, between the power shaft and the trains of gearing 16, and 17, for respectively operating the press follower and moving the perforated carrier across the press mouth.

TvVhile the main factor affecting the uniformity of the length of the sprays formed on the perforated carrier plate is the press mouth, it will be observed that the section or separation of these sprays at their terminals is effected by the moving plate operating against the distal edge G, of the press mouth. And that the relative speed of the traveling perforated plate, and of the feed of the material thereto, has an important bearing on the length of the sprays.

What I claim as my invention and desire to secure by Letters Patent is- In a machine for making food filaments, a press seat, a press mouth portion vertically opposite said seat, a device in connection with said mouth portion to facilitate the feed, a series of separable perforated {ilament-carrying plates movable over and in contact with said press mouth portion, a removable open-end press cylinder engaging said seat and said mouth portion, a screwoperated follower, differential means governing the relative movements of the plates and the follower, and shifting gear for quick reversal of the follower.

In testimony whereof I aflix my signature, in presence of two witnesses.
